서버 환경

CentOS 6.5

TOMCAT 7

java version "1.7.0_55"

1. 간단하게 vi catalina.sh 또는 vi setenv.sh 설정함

----------------------------------------

CATALINA_OPTS="$CATALINA_OPTS

-Djava.rmi.server.hostname=xxx.xxx.xxx.xxx 

-Dcom.sun.management.jmxremote

-Dcom.sun.management.jmxremote.port=9080

-Dcom.sun.management.jmxremote.rmi.port=9081

-Dcom.sun.management.jmxremote.authenticate=false

-Dcom.sun.management.jmxremote.ssl=false"

----------------------------------------

2. 인증 방식 넣기 (설정시 access,password파일 추가등록)

------------------------------------------------

CATALINA_OPTS="$CATALINA_OPTS

-Djava.rmi.server.hostname=xxx.xxx.xxx.xxx 

-Dcom.sun.management.jmxremote

-Dcom.sun.management.jmxremote.ssl=false

-Dcom.sun.management.jmxremote.port=9080

-Dcom.sun.management.jmxremote.rmi.port=9081

-Dcom.sun.management.jmxremote.authenticate=true

-Dcom.sun.management.jmxremote.access.file=$CATALINA_HOME/conf/jmxremote.access

-Dcom.sun.management.jmxremote.password.file=$CATALINA_HOME/conf/jmxremote.password

------------------------------------------------

※ 계정등록 ( 구글링해보니까 LDAP 연동 방법도 있는 듯 필요시 구글링해볼것!! )

https://code.google.com/p/tungsten-replicator/source/browse/trunk/commons/conf/sample.jmxremote.access?spec=svn1148&r=1148

vi jmxremote.access ( 계정에 맞게 readonly 또는 readwrite )

------------------------------------------------

admin readwrite \

      create javax.management.moitor.*,javax.management.timer.* \

      unregister

------------------------------------------------

vi jmxremote.password

------------------------------------------------

admin password

------------------------------------------------

3. 에러발생시 처리 방안

※ Error: Exception thrown by the agent : java.net.MalformedURLException: Local host name unknown: java.net.UnknownHostException: dev-was01: dev-was01: Name or service not known

 => vi /etc/hosts 아래 host 추가하면됨

     127.0.0.1   localhost dev-was01

※ shutdown시 Error: Exception thrown by the agent : java.lang.NullPointerException

 => CATALINA_OPTS 아닌 JAVA_OPTS 에 넣으면 Exception 에러발생

 => http://archive.apache.org/dist/tomcat/tomcat-7/v7.0.53/bin/extras/

4. Apache 메뉴얼 listener was configured in server.xml 추가하는 방법

URL : http://tomcat.apache.org/tomcat-7.0-doc/config/listeners.html

Using file-based Authentication and Authorisation

If this listener was configured in server.xml as:

  <Listener className="org.apache.catalina.mbeans.JmxRemoteLifecycleListener"
          rmiRegistryPortPlatform="10001" rmiServerPortPlatform="10002" />

with the following system properties set (e.g. in setenv.sh):

  -Dcom.sun.management.jmxremote.password.file=$CATALINA_BASE/conf/jmxremote.password
  -Dcom.sun.management.jmxremote.access.file=$CATALINA_BASE/conf/jmxremote.access
  -Dcom.sun.management.jmxremote.ssl=false

$CATALINA_BASE/conf/jmxremote.password containing:

admin letmein

$CATALINA_BASE/conf/jmxremote.access containing:

admin readwrite

then opening ports 10001 (RMI Registry) and 10002 (JMX/RMI Server) in your firewall would enable jconsole to connect to a Tomcat instance running behind a firewall using a connection string of the form:

service:jmx:rmi://<hostname>:10002/jndi/rmi://<hostname>:10001/jmxrmi

with a user name of admin and a password of letmein.

개발후 배포시 war로 압축해서 배포하는 그때

서버환경(개발/운영)에 따라서 DB접근 정보나 기타 cfg 설정이 다른 경우가 있다

그런 경우 PropertyPlaceholderConfigurer등 설정 정보를 다르게 보게 해야되는 데

구글링 해보니까 아래 Stackoverflow 몇가지를 제시하고있다. 

http://stackoverflow.com/questions/11735526/spring-loading-application-properties-based-on-tomcat-servlet-contect-definition

그중에 괜찮다고 생각되는 두가지 방안

1. 아래 방법처림 배포될 서버에 예상해서 설정해서 여러개로 구성하는 방법

<bean class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
    <property name="locations">
        <list>
            <value>classpath:your-production-config.properties</value>
            <value>file:C:/Users/${user.name}/test-application.properties</value>
        </list>
    </property>
    <property name="ignoreUnresolvablePlaceholders" value="true"/>
    <property name="ignoreResourceNotFound" value="true"/>
    <property name="systemPropertiesModeName" value="SYSTEM_PROPERTIES_MODE_OVERRIDE"/>        
</bean>

2. ${catalina.home} 변수 이용한 Tomcat 디렉토리의 conf에 설정을 따로 구성해두는 방안

<context:property-placeholder location="file:${catalina.home}/conf/myFirst.properties" ignore-unresolvable="true" />
<context:property-placeholder   location="classpath:second.properties"  ignore-unresolvable="true"  />
<bean class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
<property name="locations">
    <value>file:${catalina.home}/conf/dbpool.properties</value>
</property>
</bean>

개발환경에서 한개 서버에 버젼에 따라서 여러 톰캣을 띄워야 할 경우에는 2번 방법이 괜찮은 것 같다.

1. JDK 설치 안되었을때 설치할것!!
yum list java*jdk-devel
yum install java-1.7.0-openjdk-devel.x86_64

2. Tomcat 다운로드

http://tomcat.apache.org/download-70.cgi

wget http://apache.tt.co.kr/tomcat/tomcat-7/v7.0.53/bin/apache-tomcat-7.0.53.tar.gz

tar xvfz apache-tomcat-7.0.53.tar.gz 

cd apache-tomcat-7.0.53/bin/

./startup.sh  <==실행

./shutdown.sh <==종료

※ JDK 설치하고 Binary Distributions 다운받아서 실행하면 끝
